This invention relates to a pleasure swing of the rider-propelledV type intended especially for use by children, and therefore designed with particular attention to .ease

and safety of operation. Itconsists ofcertain elements and features of construction in combination, as herein shown and described and as indicated by the claims.

In the drawings z' Figure 1 is in the nature of a vertical sec-y tion but shows most of the swin in side elevation, section being taken as indicated at line, 11, on Figure 2.

Figure 2 is an end elevation of the swing and portions of its supporting frame.

F igure is a top p an view of the swing carriage taken as a section as indicated at the line, 3 3, on Figure 2.

Figure 4 is a detail section of the operating lever taken as indicated at line4f% on Fi ure 1. .u v

igure 5'is a detail vertical section as indicated at line, 5-5, on Figure 1.

Figure 6 is a detail section of the hanger mounting as indicated at line, on

Figure l As shown in the drawings, the supporting frame for the swing comprises posts, 1, 1 disposed in vertical planes at both sides o the swing carriage and sloping upwardly and convergently for connection vwith 'head castings, 2-2, which in turn are transversely joined by a large tubular cross bar, 1),V and a smaller cross bar, 4, as indicated in Figures 1 and 2. At each, side of the frame the head casting, 2, is made in two lparts separable at the vertical median plane which is common to the crossfbars, 3 and 4, and the. two parts are clamped together by bolts, 5, to embrace 4 said cross members, 3 and 4.- (blique braces, 6extend downwardly and outwardly from the head castings 2, being connected thereto by terminal sockets,7, formed .with

clamping collars, 8, which engage the lateral-k ly projecting ends of the cross .bar 3.y The 1929. sensi No. 408,909.

supporting v:iframe thus consists of two sets of three legged structures spaced apart by the parallel vertical planes of the uprights, 1, and tied together by the cross bars,3 and 4, at their upper ends. The lower ends of the post membersmay be anchored in any convenient manner; they are shown withV foot sockets, 9, which may be secured to a wooden or concrete floor or otherwise firmly fastened in the ground according to circumstances of location. `The cross bars, 3 and 4, may be of any desired length, as indicated by the broken representation of these parts in Figure 2; in some cases a single set of uprights 'may support two or three swing carriages.` To stien the construction and also to support the swing carriage I provide hanger brackets between the bars, 3 and 4 in the form ofsplit clamps, 10, of triangular form secured .by clamping bolts, 10a., in spaced relation on the cross bars, 3 and 4.

The swing carriagey comprises a seat plank,

11, to the underside of which are attached brackets, l2, supporting foot boards, 13, at

each side of the plank, 11, and tied togetherV laterally by cross bars, 14; sloping braces, 12a, may also be provided at vthe middle of the carriage. Sloping foot rests, 15, are slidably secured to the foot boards, 14, by means of guide straps, 16, and each 'of them is ad- :ustable longitudinally by the insertion of a pin, 17, on the under side of the foot rest in one of a series of holes, 18, inthe foot board, 13. y v

To the upper side of the seat plank, 11, a rigid frame is secured consisting of uprights, 20, spaced apart laterally in pairs, each pair being connected to each other in any suitable manner as by integral diagonal portions, 21, and horizontal bars, 22'; the upper ends of the uprights, 20, are formed with bosses, 25, to carry pivot bolts, 26, whereby the rigid carriage structure is attached to hanger bars, 27, dependent fromtriangular yokes, 28, attached to their upper ends. The uprights are 23, with spacing ofthe Hangers, 27, about the pivots, 26, 'takes place at a point far enough abovetheseat plank, 11, to avoid any danger of 'striking the heads .of the riders.

or operation of the swing thellianger bars, 27 are extended downwardly below the pivots,.26 at 31 and these depending portions.

are pivotallyconnected to a horizontal operating member, 32, with handles, 33, mounted ,at itsends. The member, 32,-remains parallellm the seat plank, 11, throughout the movement of the swing, but moves longitudinally with respect to the seat so that as the riders exert pressure or pull horizontally upon the handles, 33, they tend to move thehangers, 27, away from strictly vertical positions, and thus produce the swinging motion of the carriage. The member, 32, consists of two similar halves separable at a vertical plane and connected by tie bolts, 34. Pivot sleeves, 35, are secured between'the halves of the4 part, 32, by screws, 36, and bushings, 37,

carried by the "extensions, 31, ofthe hanger bars, 27, provide the pivotaly bearings between these parts. To permit of varying the leverage fil-*mechanical advantage of the operating member, 32, I prefer to arrange lseveral bushings, 37, in the: lowerv ends, 31,` of the hangers, 27 ,'so that the pivot sleeves, 35, vmay be shifted from one set of bushings to another whenvdesired. As shown in Figure 5 the pivots, 35, are-engaged in the'lowest of the three bushings, 37;- for connection with the upper bushings the member, `32, may be turned upside-down to provide proper clearance ofthe parts for operation.` Thus for smaller childrenthe member, 32, is connected in the lowest bushings, 37, thus bringin the, handles, 33,- convenientlyl nearthe seatfp ank,

' 11, and, providing the greatest ymechanical P' advantage in operation, while for larger children the handles, 33, may be raised yto a position farther from the seat and by connection with one of the upper sets of bushings,

Y 37," will provide a shorter leverage by which the larger and stronger children can loperate the swing witha somewhat shorter workingstrokeir- ,Y t

The sides of the operating member, 32, are

'fitted between the uprights, 20, of the car- Owing to the connection of riage frame with only slight clearance so that there is little chance that the riders will catch their fingers between these parts, particularly since there is no occasion for placing the hands on the portion of the member, 32, which travels back and forth between the uprights, 20. The travel of the member, moreover, is always in a direction perpendicular to the edges of the uprights, 20, so that thereris no wedging or pinchingV actiony possible between these partsfthe member, .32,to the lower ends, 3l, ofthe hangers, 27, tlfemotion of'v the operating part,y 32, is in the same' direction as that of the swing carriage so `that the inertia of any body move- 1s added tosuch eilforts and renders the operation of the swing easier and more natural thanvif the body lmotion were opposite to the direction of swing movemen `Alsa'fe'ty feature to prevent injury to bystanders who might come too close to the path of the swing carriages is provided in the form of-rubber armoured Vbuer wheels or disks, 38, attached to the under side of the seat plank at each end, preferably on pivots, 39, which are not rigidly secured to the seat plank but are attached thereto by coiled spring mountingmembers, 40, 'so that the bu'er wheels, 38,:will yield bodily upon colliding with a person in the path of the swing and thus avoiding serious injury.

Various changes may be made in the embodiment' of the invention herein specifically described `without departing from or sacriiicing any advantages thereof as defined in the appended claims.
